I will fix your lovable app, bolt new or vibe code and secure your supabase backend
Ziad Karim
About this gig
Need to fix your Lovable app, Bolt.new project or any vibe coded app that is buggy, slow or not safe to launch? I'll fix the code and lock down your Supabase backend so real users can sign up and pay without surprises.
I'm a Senior Software Engineer (Node.js, TypeScript, React, SQL), so as your Lovable expert I fix the root cause, not just the error message.
WHAT I FIX
- Build errors, broken pages and AI-generated bugs
- Supabase Row Level Security (RLS) policies and auth
- Exposed API keys moved to Edge Functions or server code
- Slow queries, missing indexes and storage rules
- Stripe payments, webhooks and email flows
- Deploy to Vercel or Netlify with a custom domain
WHO IT IS FOR
- Founders who vibe coded an MVP in Lovable, Bolt, Cursor or Replit and need it production ready
- No-code builders stuck in an AI fix loop
YOU GET working code pushed to your GitHub repo and a short report of every fix and security change.
Message me the problem before ordering for a quick review.

FAQ
Which platforms do you work with?
Lovable, Bolt.new, Cursor, Replit, v0, Base44 and hand-written React / Next.js apps, with Supabase, Firebase or Postgres backends.
Can you fix my Lovable app if Lovable's AI keeps breaking it?
Yes. That AI fix loop is the most common problem I solve. I fix the code directly in your GitHub repo, then you can keep building in Lovable.
Is my Supabase app secure?
Many AI-built apps ship with RLS disabled or API keys in the browser, which can expose user data. The Standard package includes a full RLS and auth audit with fixes.
What do you need from me?
Access to your GitHub repo or the Lovable/Bolt project, a Supabase collaborator invite, and a list of the bugs or features. I never need your personal passwords.
What if I am not sure how many bugs there are?
Send me a short description of the problem. I'll review it and recommend the right package before you order.
Can you add new features too?
Yes. Payments, roles, dashboards, emails and API integrations are common. Premium covers one major feature, or I can send a custom offer.
